The objective: to assess the prognostic significance of the level of serum hyperglycosylated human chorionic gonadotropin (gHCG) reative to the development of pregnancy complications that lead to impaired fetal conditions.

Materials and methods. 382 pregnant women were examined who were on the register, were hospitalized in case of complications of pregnancy and gave birth to KCMH №2 (Kiev). All pregnant women were evaluated serum gCGG in the period of 8-10 weeks gestation, evaluated the course and result of pregnancy.

Results. Reduction in the level of gHCG is a marker of insufficient trophoblast invasion, which is likely to lead to the formation of placental dysfunction and the development of a variety of obstetric pathology complicating the course of pregnancy and a risk factor for antenatal loss and neonatal morbidity.

The conclusion. Determination of the level of hyperglycosylated human chorionic gonadotropin in the first trimester of pregnancy will make it possible to identify pregnant women at risk for the formation of placental dysfunction and propose a set of monitoring activities aimed at early detection of violations of pregnancy and their timely removal. This helps prevent the formation of severe pathological conditions during pregnancy in both the mother and the fetus, which corresponds to the current trends in the development of medical care, namely: prediction, prevention and individual approach.
